The Ferdiad Cycle

Maponos

Maponos is the god of the ocean and river, believed to reside beneath the waves of the Endless Sea. He created language and numbers which his daughter Blodeuwedd stole from him to give to the humans. He waters are his to command, both beneficial and destructive. In addition he is the god of freedom, literacy and mathematics. His essence is wisdom.

His temples are always located by water, some even atop the waves like in the case of the temple-ships floating across the rivers. The priests are trained decades in the various classic subjects and often keep impressive libraries.
